PEN-CLAMP FOR RULING-MACHINES.

Specification of Letters Patent.

Patented Feb. 2'7, 1917.

Application filed August 21, 1916. Serial No. 115,970.

To all whom/it mayponcem:

Be it known that I, GEORGE VAN Wonivrnn, a citizen of the United States, and residlng at Hamilton, in the county of Butler and State of Ohio, have invented new and useful inijn-ovements in Pen-Clamps for Ruling-Machines, of which the following specification. is a full disclosure.

My invention relates to a pen clamp for element adapted to forcibly draw the jaws together in a pen-clamping operation.

Various other objects relate to the arrangement and combination of parts affording a very durable structure conveniently disassembled for cleaning and adjusting.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan view. Fig. 2 is a plan view of one of the jaw members looking at its inner surface. Fig. 3 is a similar plan view of the opposite jaw member. Fig. 4: is a section on line 41, Fig. 1. Fig. 5 is a right hand elevation. Fig. 6 is a section on line 6-6, Fig. 1.

The clamp comprises two rectangular sections Or jaws 1, 2, the section 1 extending beyond the section 2, as at 3, to provide means for connecting the clamp to the cross beam of the ruling machine in the usual or any preferred manner. Embedded in the inner surface of the section 1 is a retaining plate 4: provided at intervals with rectangular apertures through which a series of eyeplates 5 project, the base portion of said eye-plates being embedded in the section 1 and shouldered as at 66 to securely retain the plates in position. Secured to and embedded in the outer surface of one end of the section 1 is a plate 7 which extends beyond the section 1 providing a support for the adjusting or clamping screw 8. Extending laterally from the plate 7 is an eye-plate 9 similar in form to the eyeplate 5.

The section 2 has a bearing plate 10 embedded in its outer surface and said plate and the section 2 are provided with rec'- tangular apertures, relatively spaced so as to register with the eye-plates 5 of the section 1 when'the two sections are assembled. iVhen the sections are assembled, the eyeplates 5 of the section 1 extend through the alined apertures of the section 2 and beyond the outer surface of the bearing plate 10.

An oscillating shaft or rod 11 extends through the eye-plates 5 and 7 and has a fiat surface 12 normally resting on the bear ing plate 10. The end ofthe rod 11 is squared and has secured to it, an arm 13, adapted to be engaged and rocked by the clamp screw 8. The clamp screw extends through a screw-threaded opening in the plate 9 and carries'a lock-nut 14 to lock the screw against accidental rotation. The sections are normally held in separated relation by a pair of leaf springs 1515 which are secured to the inner surface of the section 2 and bear against the retaining plate 4 of the section 1.

To clamp the pen in position between the two sections or jaws, the clamp screw 8 is rotated to oscillate or rock the rod 11 which, by reason of its flattened surface engaging the bearing plate 10 of the section2 and its rounded surface engaging the eye-pieces of the section 1, will tend to force the sections together in opposition to the tension of the springs 1515.

Having described my invention, Iclaim 1. A pen clamp for ruling machines comprising two clamp sections, means normally separating the sections, eye-plates extending from one of said sections, an oscillating element engaging through said eye-plates in operative contact with the second section, and means for rocking the oscillating element to move the sections toward each other in a clamping operation.

2. A pen clamp for ruling machines comprising two clamp sections, one of said sections having transverse projections, an oscillating element intermediate the transverse projections of the one section, and an outer surface of the second section, and means for rocking said element to force the two sections together.

3. A. clamp for ruling machines comprising two clamp sections, eye-plates extending transversely from one of the sections, an operating rod extending through the eyeplates, and having a flat side normally engaging the outer surface of the second section, and means for oscillating the rod to force the sections together.

4:. A clamp for ruling machines comprising an apertured section and a second section having transverse eye-plates in registry with the apertures of the first-namec section, an operating shaft positioned adjacent an outer surface of the apertured section and engaging through the eve-plates of 10 the second section, and means for oscillating the shaft to force the two sections together.

In Witness whereof, I hereunto subscribe my name, as attested by the two subscribing Witnesses.
